I Think Our Imac Is Dying
Bluetooth not available

Mac froze up and all I had was a black screen with the 'spinning beach ball of death' a few minutes ago. Hard powered off the iMac by holding down the power button until it powered off then powered it on again.

After logging in noted that my Magic Trackpad was no longer working, checked the Bluetooth icon at the top of the screen and status is "Bluetooth: Not available". Ok thought to myself lets zap the PRAM, rebooted held down Command+Option+P+R and got the second start up chime, released the keys and the machine once again came back to a log on screen after a few minutes. Logged in ans still have no Bluetooth available which makes me suspect some kind of hardware fault and I am nervous as to what is going to stop working next.

I'd welcome any suggestions on what to do, machine is a few months out of Apple Care which expired around May this year. We really cannot afford to have to buy a new machine and the moment so any suggestions would be welcome - if it just stays as dead Bluetooth then that's OK at least I can still use the machine, just not any Bluetooth devices! But if it might be indicative of some other problems that I'm yet to experience I think I'd like to know in advance.

Eureka! It's working again now. As a last ditch attempt this morning I shut down the Mac, removed the mains power cord and left unplugged for about a minute and then plugged it in again and powered up. The Mac booted and at the logon screen showed the image of the track-pad with the word "connected" underneath it. Logged in and all is now back to normal.

Hopefully it was just a one off thing and the Mac will keep going for quite a while yet!
